A ril 30, 1940. .1. F. SULLIVAN WEIGHT REGULATOR FOR GOLF CLUB HEADS Filed Aug. 12, 1938 JOHN E SULLIBI/AN BY ATTORNEY Patented Apr. 30, 1940 PATENT OFFICE WEIGHT REGULATOR FOR GOLF CLUB HEADS John F. Sullivan, Oakland, Calif.

Application August 12, 1938, Serial No. 224,557

, 3 Claims.

This invention pertains to weight regulators for golf club heads. It is an object of the invention to provide an extremely simplified and yet efficient means for the accurate weighting of golf club heads to the end that the most exacting requirements of the individual player may be conveniently met.

Since practically the inception of the game of golf it has been the common practice of club makers and manufacturers to weight golf clubs, particular reference being had at this time to the woods as distinguished from the irons by simply boring or otherwise cutting a hole in the back of the club and tapping lead plugs thereinto. There have been innumerable objections to the practice. In the first place it has been extremely difficult, if not impossible, toweight clubs with the required degree of accuracy. In the second place the plugs become loosened and for that reason require further adjustment. In the third place the appearance of an otherwise fine piece of craftsmanship is efiaced by an apparently makeshift weighting means.

The present invention contemplates the provision of a weighting means which will overcome the aforementioned objections and in addition accomplish the desirable factor of positioning the weight where it will do the most good.

These and other objects will become more apparent as this specification proceeds and the novelty of the subject matter will be particularly pointed out in the appended claims.

In the drawing forming a part hereof,

Figure 1 is a side elevation, partly in section, 35 of a golf club head embodying my improved weight regulating means,

Figure 2 is a vertical section of a golf club head embodying my improvements,

Figure 3 is a bottom plan view of the golf club head of Figure 1,

Figure 4 is a perspective view of the weight holder of my invention,

Figure 5 is a perspective view of a weight retainer,

Figures 6 and 7 show two forms of weights for use in conjunction with. the subject matter of my invention, and

Figure 8 is a section along the lines 8-8 of Figure 1.

A golf club head ll], of wood or composition, afiixed to a conventional shaft II, has the usual sole l2. A bore [3 into the golf club head through the sole [2 is adapted to receive a plug I4. The bore is threaded as at 15 to engage the threads IE on the plug I4,

The plug M has a tubular inner end I! defining a weight receiving chamber. Weights in the form of discs of varying thickness and internal diameter, such as l8 and. 19 (see Figures 7 and 6), split as at 20, are compressed for insertion in the tubular end I! of the plug It. It will be appreciated that the weights may take a multitude of forms in addition to the two forms shown and thereforeI do not limit myself to these forms. only. For example, the weights may take the form of springs of graduated size and. weight, or in fact any desirable form of compressible material.

As a means of locking the weights I8 and I9 in the tubular end I! of the plug I4 against any possible movement I provide a retainer disc 25- having screws 26 received by the longitudinally disposed slots 21 in the tubular end I! of plug I4. Thus when the desired size and number of weights 18 or l9 have been inserted in the tube 11 of plug 14, the retainer 25 is placed therein and the screws 26 thereon are turned inwardly to lock the weights in position. I

Theretainer 25 need not be in the form of a disc, but on the contrary it may be a bar having the screws 26 at either end thereof. The plug I4 is provided with a pair of conventional recesses to receive any well known tool. In addition to serving as a means for holding the weights l8 and 19, the plug l4 serves as a sole plate for the club In (see Figs. 1-3, inclusive).

It will thus be seen that the subject matter of this invention provides an extremely eflicient means for accurately weighting golf club heads.

In the event that the player finds re-adjustment of the weight of his: woods essential to his game, such adjustment can be effected with the simplest of tools and will require but a minimum of time.

Having thus disclosed my invention, what I claim and desire to secure by grant of Letters Patent is:

1. In a weight regulator for golf club heads, a screw plug having a tubular inner end, weight means therein, a weight means retainer adjustable longitudinally within the tubular end of said screw plug, said plug having an elongated slot, and means movable in said slot operable to fasten said weight retainer to said tubular end.

2. In aweight regulator for golf club heads, a screw plug having a tubular inner end, weights therein, longitudinally extending slots in the tubular inner end of said plug, and a weight retainer member in said. tubular end of the plug having screws projecting through said longitudinal slots.

3. In a weight regulator for golf club heads, a plug having a tubular inner end, weight means therein, a weight retainer adjustable axially of said end, fastening means to secure said weight retainer in different adjusted positions, said end having slot means in its tubular wall through which saidfastening means is disposed.

JOHN F. SULLIVAN.
